Don't worry too much about the law: if the past is any guide, nobody else will. Be creative! If you have not really got the statutory power, just brazen it out.

Protect your back. Disclose your bias - but bury it in impenetrable prose nobody will read - so you can blame the politicians if you get caught. Para 1.17 of the Electoral Commission's Referendum Assessment is an excellent example, expressing concerns about the potential legitimacy, in the eyes of those campaigning to leave and some members of the public, of the referendum result - particularly if there was a vote to remain a member of the European Union. So no worries if a biased ballot leads to Brexit!

Learn tricks from the past but realise you may need to be more subtle.
